虛擬局域網(wǎng)VLAN 網(wǎng)橋/交換機(jī)的本質(zhì)和功能是通過將網(wǎng)絡(luò)分割成多個(gè)沖突域提供增強(qiáng)的 網(wǎng)絡(luò)服務(wù)，然而網(wǎng)橋/交換機(jī)仍是一個(gè)廣播域，一個(gè)廣播數(shù)據(jù)包可被網(wǎng) 橋/交換機(jī)轉(zhuǎn)發(fā)至全網(wǎng)。雖然OSI模型的第三層的路由器提供了廣播域分 段，但交換機(jī)也提供了一種稱為VLAN的廣播域分段方法。 什么是VLAN： 一個(gè)VLAN是跨越多個(gè)物理LAN網(wǎng)段的邏輯廣播域，人們?cè)O(shè)計(jì)VLAN來(lái)為工 作站提供獨(dú)立的廣播域，這些工作站是依據(jù)其功能、項(xiàng)目組或應(yīng)用而不 顧其用戶的物理位置而邏輯分段的。 一個(gè)VLAN=一個(gè)廣播域=邏輯網(wǎng)段 VLAN的優(yōu)點(diǎn)和安裝特性：
